IMPROVEMENT IN FlLTERS AND SPRINKLERS COMBlNED.

Specification forming part of Letters Patent No. 168,825, dated 0 ctober19, 1875; application filed July 6, 1875.

To all whom it may concern:

Be it known that we, JOHN BATGHELOR and ANDREW J. WARREN, both of Bridgeport, in the county of Fairfield, and in the State of Connecticut, have invented certain new and useful Improvements in Water-Filters; and do hereby declare that the followingis a full, clear, and exact description there of, reference being had to the accompanying filtering. Fig. 2 is a longitudinal half-section,

showing one-half of the entire device. Fig. 3 is a View of the strainer or sprinkler. Fig. 4 represents the lower section with.the guard in place, and Figs. 5 and 6 represent the guard detached from the casing.

A represents the coupling-thread, by which the sprinkler is attached to the hose or faucet. Brepresents the sprinkler; H, the thread by which the upper and lower sections of the casing are connected, which combines the sprinkler and filter; D, the open space for the sponge or other filteringsubstance; E, the guard which prevents the filtering substance from being forced into the dischargetube by the pressure of the water, and F the tube which forms the column of water after it is purified by the filter. This tube and the upper coupling are both made so as to receive a wrench, by which they may be firmly joined to the upper section. This joint is supplied with a suitable leather washer, as represented at O in Fig. 2. When the filter is to be used, separate the lower section from the upper one, place the guard E in the lower section, insert the sponge, and firmlyscrew the two sections together. The water being let on, the sprinkler B catches the coarser sediment when the water passes into the space D, which is entirely filled with the filtering substance. The water being thus purified, it passes out in a continuous stream at F.

have been used for filtering purposes but our guard is of such construction as that the water is formed in acompact stream without spattering, which is the fault with others; and by using first the strainer and then the sponge, we overcome the essential defect of all other filters in which a sponge is used-to wit, the sediment fills the entire cells of the sponge, and, the coarser portions remaining in JOHN BATOHELOR.
